Sex chromosome is a type of chromosome in the genome that is involved in the determination of the sex as well as the development of sexual characteristics in an organism.
In humans, there are two forms of sex chromosomes: the X chromosome and Y chromosome. A pair of X and Y results in a male while a combination of X and X results in a female. Sex chromosomes occurs in pairs in somatic cells while singly in sex cells (gametes).
